You can use Roomba 500, 600, 700 and 800 series as a base of Roomblock,which we introduced in the previous post. They have a serial port to communicate with external computers. Notice the flagship model Roomba 900 series have no serial port, so you cannot use it.
You can see the serial port as the picture shows. Be careful not to cut your fingers or break your Roomba!
In the next post, we will show how to connect Raspberry Pi computer and Roomba.
We share how to build Roomblock at Instructables. Please try it at your own risk.
